[Replacement of defects in the duodenal wall with a small intestine graft]

Experimentally on 16 dogs the terminal defect of the duodenum was replaced by a pedicled jejunal graft (one formated by incising the duodenal segment along its contramesenteric margin). In the early postoperative period 2 animals died, 2 animals are kept under observation. The remainder were sacrified for the study within the terms from 2 to 3 years postoperatively. Duodenal specimens from these animals were examined macroscopically, by vasography (with contrast medium filling of the transplant vascular system via the mesenteric pedicle artery) and microscopically using review, special and some histochemical technics of micropreparations staining. The results of the investigations performed indicate the possibility of using the technic of plastic repair of the duodenal wall defect under consideration in clinical practice too.
